Description

The TC4404COA belongs to TC4404/TC4405 family which are CMOS buffer-drivers constructed with complementary MOS outputs, where the drains of the totem-pole output have been left separated so that individual connections can be made to the pull-up and pull-down sections of the output. Minimum rise and fall times, with no resistors, will be less than 30nsec for a 1000pF load. For driving MOSFETs in motor-control applications, where slow-ON/fast-OFF operation is desired, these devices are superior to the previously used technique of adding a diode-resistor combination between the driver output and the MOSFET, because they allow accurate control of turn-ON, while maintaining fast turn-OFF and maximum noise immunity for an OFF device. They allow insertion of a base current-limiting resistor, while providing a separate half-output for fast turn-OFF. By proper positioning of the resistor, either npn or pnp transistors can be driven. For driving many loads in low-power regimes, these drivers, because they eliminate shoot-through currents in the output stage, require significantly less power at higher frequencies, and can be helpful in meeting low-power budgets. This allows the insertion of drain-current-limiting resistors in the pull-up and/or pull-down sections, allowing the user to define the rates of rise and fall for a capacitive load; or a reduced output swing, if driving a resistive load, or to limit base current, when driving a bipolar transistor. When used to drive bipolar transistors, these drivers maintain the high speeds common to other Microchip drivers.

The features of TC4404COA can be summarized as (1)independently programmable rise and fall times; (2)low output impedance 7Typ.; (3)high speed tR, tF <30nsec with 1000pF load; (4)short delay times <30nsec; (5)wide operating range - 4.5V to 18V; (6)latch-up protected: will withstand > 500mA reverse current (either polarity); (7)input withstands negative swings up to -5V.

The absolute maximum ratings of TC4404COA are (1)supply voltage: +22V; (2)power dissipation (TA 70°C), PDIP: 730mW, CERDIP: 800mW, SOIC: 470mW; (3)package thermal resistance, PDIP R J-A: 125°C/W, PDIP R J-C: 45°C/W, CERDIP R J-A: 150°C/W, CERDIP R J-C: 55°C/W, SOIC R J-A: 155°C/W, SOIC R J-C: 45°C/W,; (4)operating temperature range, C Version: 0°C to +70°C, E Version: -40°C to +85°C, M Version: -55°C to +125°C; (5)storage temperature range: -65°C to +150°C.
